Hall Effect Switch Module (44E 402)
This breakout board uses a 44E hall effect switch, which means that it has a digital output, not an analog voltage. As such you can connect it to a digital input on a microcontroller or drive buzzers, LEDs or others directly from its output.
In the absence of a magnetic field the output is high (VCC or whatever your power supply voltage is). When there is a magnetic field present the signal output goes low (0V).
- - to GND on power supply
- + to 5V on power supply
- S is digital output signal
